Ocean is the largest solar collector in the world, all countries in the world dedicated to the development and utilization of ocean energy, and thermoelectric conversion of ocean energy has drawn more attention. In this paper, N-butane was selected as working fluid of organic Rankine cycle. By using process models established based on ASPEN PLUS, Ocean Thermal Energy Conversion (OTEC) was simulated and optimized, the best evaporation temperature and condensation temperature were obtained. After detailed comparison and analysis of the generating capacity at all levels and the required heat transfer area, the best Rankine cycle progression was obtained, which has good guidance meaning to the operating condition selection and optimization of temperature difference energy power system.
